1. Assuming that you can logon with the administrator account, remove/re-add the computer to the domain. Otherwise, proceed to step 2.
2. If you can't even log on to the administrator account and are getting a message along the lines of "<computername> domain could not be found", then it sounds like your High Encryption is corrupted - probably as a result of software that was installed just prior the start of your problem. If that's the case, you need to reboot to your recovery console (or if not a startup option, boot up to the W2K CD and choose the repair option. Once the command prompt appears, you want to have a good copy of the file 'Rsaenhs.dll' on a diskette and overwrite the bad copy located at C:\WINNT\system32 and you're done. Reboot and log on as usuall. Once in, you will probably have to address the problem with the software installed that caused the problem in the first place.
Hope this helps! ________
